With these programa you can compute S- and noise parameters of
networks with PYTHON-code.
All network calculations will be done with wave matrices for
signal (S parameters) anf noise (noise parameters Fmin, Rn, CN, Gamma_opt)
without voltages and currents. There are no poles or very large values
in calculations. The algorithms are numerically very stable. Input data
are the S parameters, noise parameters and the output data too. So we
get direct information about gain, match, noise, stability, noise
circles and so on. The computing time is short, so the algorithms
can be used for optimization tasks.All programs are the PYTHON versions
of the MATLAB versions
in the same FILE Exchange directory
